BACKGROUND OF INVENTION Field of the Invention

The present invention relates generally to providing a system and apparatus for sealing a structural attachment. More specifically, the invention relates to providing the system for sealing structural attachments for solar panel mounts for rail guides.

The system utilizes an adhesive sealant to create a permanent watertight seal at any surface penetration. The system may be used for any structural attachment, fastener, mount, or other penetration that requires sealing. Typical building applications include roof penetrations and wall penetrations for cases such as roof vents, structural attachment, conduit or pipe penetrations, or electrical mounts to name a few.

The system allows the user to fasten or place any attachment over the penetration point. Sealant is then injected under pressure using, by way of example, a sealant dispenser gun, into an enclosed cavity around the penetration. The force from the sealant dispenser gun increases the pressure inside the enclosed cavity and forces all the air out through a vent hole. This ensures that the sealant completely fills all the voids and removes the air inside the enclosed cavity around the penetration. Variations of the preferred embodiment are also provided.

The system creates a permanent airtight and watertight seal that does more than just shed water around the attachment. The system also eliminates the need for standard flashing and assemblies, which may reduce installation costs. The system also eliminates the need to break the manufacturer's seal on the leading edge of roof shingles and eliminates the risk of removing nails on upper courses of shingles, which creates additional penetrations in the roof thereby making the structure more vulnerable to leaks.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, and for the purposes of explanation, numerous specific details are provided to thoroughly understand the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed. More generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention, particularly when the operation is to be implemented in software. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed embodiments may be applied. The full scope of the invention is not limited to the example(s) that are described below.

An exemplary embodiment of an attachment for sealing structural attachments for solar panel mounts for rail guides is shown in FIG. 1 in the form of a flush-type mount 100. FIG. 1 illustrates the front side of the flush-type mount 100 includes a lower portion 120 that includes a base 110 that is typically mounted and conforms to a top surface of a structure such as a roof 200 shown in FIG. 4. Throughout this description, the term “roof” can also mean “structure.” The base 110 is rounded in this embodiment, but as with other alternate exemplary embodiments shown below, the shape of the base 110 can be any suitable form. The lower portion 120 includes an opening 125 for receiving a bolt 130. The bolt 130 typically comprises a nut 131 for tightening the bolt 130 to secure the flush-type mount 100 to the roof 200 by penetrating a shaft 135 into an opening 210 on the roof 200. The lower portion 120 tapers upward and forms a generally U-shaped guide 140 that comprises a pair of members 141 and 142 extending from opposing sides of the lower portion 120, which in turn forms an aperture 160. Each of the members 141 and 142 on the guide 140 also includes a ridged surface 150. The aperture 160 is configured to receive a bolt that in turn is used to secure a mounting rail (not shown) to the ridged surface 150, which provides friction to assist the connection.

FIG. 2 illustrates the rear side of the flush-type mount 100. The lower portion 120 includes a port 170 and a vent 180. It is understood that the port 170 and the vent 180 can be located anywhere on the lower portion 120. FIG. 3, which illustrates a cross-sectional view of the flush mount 100, shows that the port hole 170 and the vent 180 provide access to a cavity 127. The cavity 127 provides a reservoir for sealant 175 that is injected into the port 170 by way, for example, of a sealant gun 300 as shown in FIG. 6. An optional seal 115 is provided along the perimeter of the base 110, and the bottom of the cavity 127 typically should cover the entire surface area within the base 110 and the optional seal 115. The vent 180 enables excess air inside the cavity 127 to be released as sealant 175 is injected into the cavity 127 so that the sealant 175 can cover the full surface area along the base 110 and seal the flush-type mount 100 to the surface of the roof 200 to prevent any liquid from leaking into the roof 200 where the flush-type mount 100 is secured.

FIGS. 4-6 illustrate the steps of installing the flush-type mount 100 to the roof 200. FIG. 4 shows a top view of the roof 200. The first step in installing the system is to bore a pilot hole 210, typically with a drill, into a roof shingle on the roof 200 and fill it with sealant 175. FIG. 5 shows an exploded view of the flush-type mount 100 being installed. The next step is to place the mount 100 over the pilot hole 210 and secure the mount 100 by inserting the bolt 130 into the opening 125 and tightening it by rotating the nut 131 until the shaft 135 is fully inserted into the pilot hole 210. Once secured, as shown in FIG. 6, the sealant gun 300 is used to inject sealant 175 into the port hole 170. The cavity 127 is filled with sealant 175 until the sealant 175 begins to escape out of the vent 180 on the mount 100. When the sealant 175 begins to escape, it provides visual notice that the cavity 127 has been filled with sealant 175, thereby sealing the mount 100 to the roof 200.

This form of securing and sealing attachment mounts is also provided in various alternate embodiments. One exemplary embodiment is a standoff-type attachment/mount 400 as shown in FIG. 7. The standoff-type 400 includes a base 410 and a pair of openings 425 (shown in FIG. 8) on opposite sides of the base 410 for bolts 430 to secure the standoff-type mount 400 to the roof 200. Each bolt 430 also has a shaft 435 extending downward and a threaded portion 437 on the shaft 435. The standoff-type mount 400 includes a support 440 with a port hole 470 and outer threads 442 that are used to receive an attachment 500 as shown in FIG. 11. The support 440 and base 410 form a hollow cavity 427 that is accessible by the port hole 470. An optional thread patch 450 is also included that assists in restricting the movement of the attachment 500 when it is rotated onto the support 440.

FIGS. 8-11 illustrate the steps of installing the standoff-type mount 400 to the roof 200. Like with the flush-type mount 100, the first step in installing the system is to bore pilot holes 210, typically with a drill, into a roof shingle on the roof 200 and fill it with sealant 175. FIG. 8 shows an exploded view of the standoff-type mount 400 being installed. The next step is to place the mount 400 over the pilot holes 210 and secure the mount 400 by inserting the bolts 430 into the openings 425 and tightening each bolt 430 by rotating the nut 431 until the shaft 435 is fully inserted into the pilot hole 210. FIG. 9 illustrates further details of the standoff-type mount 400. An optional sealing lip 455 that surrounds the inner surface of the cavity 427 is shown.

Once secured, as shown in FIG. 10, the sealant gun 300 is used to inject sealant 175 into the port hole 470. In this embodiment, the port hole 470 can act both as a port hole 470 and a vent. The cavity 427 is filled with sealant 175 until the sealant 175 begins to escape out of the port hole 470 on the mount 400. When the sealant 175 begins to escape, it provides visual notice that the cavity 427 has been filled with sealant 175, thereby sealing the mount 400 to the roof 200. As shown in FIG. 11, once the mount 400 has been sealed to the roof 200, the attachment 500 can be coupled to the support 440, typically by rotating it along the threaded portion 437 until it is fully tightened.

Another exemplary embodiment is a tile-hook attachment/mount 600 as shown in FIGS. 12 and 13. The tile-hook mount 600 includes a base 610 and a pair of openings 625 (shown in FIG. 13) on opposite sides of the base 610 for bolts 630 to secure the tile-hook mount 600 to the roof 200. Each bolt 630 also has a shaft 635 extending downward and a threaded portion 637 on the shaft 635. The tile-hook mount 600 includes an attachment mount 620 that extends from the base 610 in a general L-shape. The end of the attachment mount 620 forms an apparatus similar to that shown in the flush-type mount 100 with a generally U-shaped guide 640 that comprises a pair of members 641 and 642 extending from opposing sides of the lower portion of the attachment mount 620, which in turn forms an aperture 660. Each of the members 641 and 642 on the guide 640 also include a ridged surface 650. The aperture 660 is configured to receive a bolt that in turn is used to secure a mounting rail (not shown) to the ridged surface 650, which provides friction to assist the connection.

The base 610 also includes a port hole 670. As shown in FIG. 13, the base 610 comprises a hollow cavity 627 that is accessible by the port hole 670. Once secured, as shown in FIG. 13, the steps of use are similar to the previously discussed mounts. Pilot holes 210 are bored, typically with a drill, into the roof 200 and the holes 210 are filled with sealant 175. The sealant gun 300 is used to inject sealant 175 into the port hole 670. In this embodiment, the port hole 670 can act both as a port hole 670 and a vent. The cavity 627 is filled with sealant 175 until the sealant 175 begins to escape out of the port hole 670 from the base 610 on the mount 600. When the sealant 175 begins to escape, it provides visual notice that the cavity 627 has been filled with sealant 175, thereby sealing the mount 600 to the roof 200.

Another exemplary embodiment is a universal flush mount 700 as shown in FIGS. 14-16. The universal flush mount 700 includes a base 710 and an opening 725 (shown in FIG. 16) in the middle of the mount 700 for a hanger bolt 730 that is used to secure the universal flush mount 700 to the roof 200. The hanger bolt 730 also has a shaft 735 extending downward and a threaded portion 737 on the shaft 735. The universal flush mount 700 includes an optional seal 715 that extends around the perimeter of the base 710. A washer 760 may be coupled between the top end of the hanger bolt 730 and the top surface of the base 710 to provide a tighter seal.

The base 710 also includes a port hole 770 on its top surface. As shown in FIG. 16, the base 710 comprises a hollow cavity 727 that is accessible by the port hole 770 and a vent 780 that are both typically on the top surface of the base 710. The port hole 770 is typically larger than the vent 780, although the port hole 770—like the other port holes as discussed herein, should be capable of fitting a sealant injection device like the sealant gun 300 as shown herein. As shown in FIG. 17, a pilot hole 210 is drilled into the roof 200 and the hole 210 is filled with sealant 175. The hanger bolt 730 is then inserted through the opening 725 and is tightened until the mount 700 is secured to the roof 200. Once secured, as shown in FIG. 18, the steps of use are similar to the previously discussed mounts. The sealant gun 300 is used to inject sealant 175 into the port hole 770. The cavity 727 is then filled with sealant 175 until the sealant 175 begins to escape through the port hole 780 from the base 710. When the sealant 175 begins to escape, it provides visual notice that the cavity 727 has been filled with sealant 175, thereby sealing the mount 700 to the roof 200.

Another exemplary embodiment is a universal base mount 800 as shown in FIGS. 19 and 20. The universal base mount 800 includes a base 810 and an opening 825 (shown in FIG. 20) in the middle of the mount 800 for a bolt 830 that is used to secure the universal base mount 800 to the roof 200. The bolt 830 also has a shaft 835 extending downward and a threaded portion 837 on the shaft 835. The universal base mount 800 also includes a plurality of internally threaded apertures 890 that are used to secure a mount (not shown) to the universal base mount 800. The mount 800 also includes an optional seal 815 that extends around the perimeter of a cavity 827 within the base 810. A washer 860 may be coupled between the top end of the bolt 830 and the top surface of the base 810 to provide a tighter seal.

The base 810 also includes a port hole 870 on its top surface. As shown in FIG. 20, the base 810 comprises the hollow cavity 827 that is accessible by the port hole 870 and a vent 880 that are both typically on the top surface of the base 810. The port hole 870 is typically larger than the vent 880, although the port hole 870—like the other port holes as discussed herein, should be capable of fitting a sealant injection device like the sealant gun 300 as shown herein and are typically positioned on opposite sides of the base 810. As shown in FIG. 21, a pilot hole 210 is bored, typically with a drill, into the roof 200 and the hole 210 is filled with sealant 175. The bolt 830 is then inserted through the opening 825 and is tightened until the mount 800 is secured to the roof 200. Once secured, as shown in FIG. 22, the steps of use are similar to the previously discussed mounts. The sealant gun 300 is used to inject sealant 175 into the port hole 870. The cavity 827 is then filled with sealant 175 until the sealant 175 begins to escape through the port hole 880 from the base 810. When the sealant 175 begins to escape, it provides visual notice that the cavity 827 has been filled with sealant 175, thereby sealing the mount 800 to the roof 200.

Another exemplary embodiment is a conduit mount 900 as shown in FIGS. 23-25. The conduit mount 900 typically supports a conduit 1000, which can be of any suitable shape such as a cylindrical pipe as shown in FIG. 28. As shown in FIG. 23, the conduit mount 900 includes a base 910 and an opening 925 (shown in FIG. 24) in the middle of the mount 900 for receiving a bolt 930 that is used to secure the conduit mount 900 to the roof 200. The bolt 930 also has a shaft 935 extending downward and a threaded portion 937 on the shaft 935. The base 910 typically tapers upward and forms a generally U-shaped guide that comprises a pair of members 945 and 946 extending from opposing sides of the base 910, which in turn forms an opening 920 configured to receive the conduit 1000. Each of the members 945 and 946 also includes a threaded aperture 940 and 941 respectively. The apertures 945 and 946 are configured to receive a securing bolt 950 that is threaded 955.

The base 910 also includes a port hole 970 on its outer surface. As shown in FIG. 25, the base 910 comprises the hollow cavity 927 that is accessible by the port hole 970 and a vent 980 that are both typically on the outer surface of the base 910. The port hole 970 is typically larger than the vent 980, although the port hole 970—like the other port holes as discussed herein, should be capable of fitting a sealant injection device like the sealant gun 300 as shown herein and are typically positioned on opposite sides of the base 910. As shown in FIG. 26, the bolt 930 is inserted through the opening 925 and is tightened until the mount 900 is secured to the roof 200. Once secured, as shown in FIGS. 27 and 28, the steps of use are similar to the previously discussed mounts. The sealant gun 300 is used to inject sealant 175 into the port hole 970. The cavity 927 is then filled with sealant 175 until the sealant 175 begins to escape through the port hole 980 from the base 910. When the sealant 175 begins to escape, it provides visual notice that the cavity 927 has been filled with sealant 175, thereby sealing the mount 900 to the roof 200. Once the conduit mount 900 is secured to the roof 200, the conduit 1000 can be inserted through the opening 920 and secured to the mount 900 by using the second bolt 950 and tightening it through the apertures 940 and 941 using the threaded portion 955 of the second bolt 950.

Another exemplary embodiment is a conduit riser attachment 1100 as shown in FIGS. 29-31. The conduit riser 1100 typically fits over a conduit that rises through the roof 200 through a conduit hole 240 as shown in FIG. 33. The conduit riser 1100 includes a base 1110, that extends upward to a top end with a conduit gasket 1120 on the top end that surrounds an opening 1115 that is configured to receive a conduit 1200 as shown in FIG. 30.

The base 1110 also includes a port hole 1170 on its outer surface. As shown in FIGS. 29-31, the base 1110 comprises the hollow cavity 1125 for holding sealant 175 and is accessible by the port hole 1170 and a vent 1180 that are both typically on the outer surface of the base 1110. The port hole 1170 is typically larger than the vent 1180, although the port hole 1170—like the other port holes as discussed herein, should be capable of fitting a sealant injection device like the sealant gun 300 as shown herein and are typically positioned on opposite sides of the base 1110.

As shown in FIG. 32, the conduit hole 240 is bored into the roof 200. The conduit 1200 is then attached to a rafter in an attic (not shown) below the roof 200. The conduit riser 1100 is then placed over the conduit 1200 as shown in FIG. 33 until fully seated on the roof 200. The sealant gun 300 is used to inject sealant 175 into the port hole 1170. The cavity 1127 is then filled with sealant 175 until the sealant 175 begins to escape through the port hole 1180 from the base 1110. When the sealant 175 begins to escape, it provides visual notice that the cavity 1127 has been filled with sealant 175, thereby sealing the conduit riser 1100 to the roof 200. Once the conduit riser 1100 is secured to the roof 200, the process is complete.
